Notes:
The purpose of this study is to examine the inhibitory effects of nano-HA on thecaries-inducing properties of a four-organism bacterial consortium in vitro. A series of in vitroanticarious experiments have been carried out by using a continuous culture system. Streptococcusmutans, Streptococcus sanguis, Actinomyces viscosus, Lactobacillus rhamnosus have been chosen asthe experimental bacteria. After 48 hours, the dental plaque surface structure is observed with thescan electron microscope and the bacterial colonization was evaluated on dental plaque. The resultsshow that Spherical nano-HA and mixed nano-HA are proved to be effective in anticariousexperiments, and especially spherical nano-HA is more striking. It is able to damage the formation ofbiofilms (dental plaque), postpone or end the process of acid generation of bacteria metabolism. After7 days, the demineralization of the enamel has been detected by using TEM. The spherical nano-HAmight have a remineralization to early caries to prevent and decrease caries
